Six groups of colloids\/particles in the range 5\u2009nm to 5\u2009\u00b5m were determined (in decreasing order of abundance): carbonates, phyllosilicates (clay minerals and micas), quartz, Fe-oxides, organics and others (salts, phosphates). Inorganic colloids\/particles in leachates from the active landfill predominantly consist of calcite (CaCO\n                    <jats:sub>3<\/jats:sub>\n                    ) and minor clay minerals and quartz (SiO\n                    <jats:sub>2<\/jats:sub>\n                    ). The colloids\/particles in the leachates from the closed landfill consist of all the observed groups with dominant phyllosilicates. Whereas calcite, Fe-oxides and phosphates can precipitate directly from the leachates, phyllosilicates and quartz are more probably either derived from the waste or formed by erosion of the geological environment of the landfill. Low amounts of organic colloids\/particles were observed, indicating the predominance of organic molecules in the \u2018truly dissolved\u2019 fraction (fulvic compounds). Especially newly formed calcite colloids forming particles of 500\u2009nm and stacking in larger aggregates can bind trace inorganic contaminants (metals\/metalloids) and immobilize them in landfill environments.\n                  <\/jats:p>","DOI":"10.1177\/0734242x11408382","type":"journal-article","created":{"date-parts":[[2011,6,8]],"date-time":"2011-06-08T00:11:17Z","timestamp":1307491877000},"page":"530-541","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Transmission electron microscopy investigation of colloids and particles from landfill leachates"],"prefix":"10.1177","volume":"30","author":[{"given":"Marek","family":"Matura","sequence":"first","affiliation":[{"name":"Institute of Geochemistry, Mineralogy and Mineral Resources, Charles University in Prague, Faculty of Science, Praha, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vojt\u011bch","family":"Ettler","sequence":"additional","affiliation":[{"name":"Institute of Geochemistry, Mineralogy and Mineral Resources, Charles University in Prague, Faculty of Science, Praha, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Klementov\u00e1","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry of the AS CR, Husinec-\u0158e\u017e, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,6,7]]},"reference":[{"key":"bibr1-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.watres.2006.04.049"},{"key":"bibr2-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1177\/0734242X04042146"},{"key":"bibr3-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1021\/es00009a004"},{"key":"bibr4-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1021\/es980217h"},{"key":"bibr5-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1021\/es060255y"},{"key":"bibr6-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.gca.2008.01.002"},{"key":"bibr7-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1007\/s10646-008-0213-1"},{"key":"bibr8-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/S0043-1354(97)00202-9"},{"key":"bibr9-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1021\/es901912g"},{"key":"bibr10-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1039\/b413832e"},{"key":"bibr11-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1002\/9780470024539.ch3"},{"key":"bibr12-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1007\/s00254-005-0110-3"},{"key":"bibr13-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.gexplo.2005.08.010"},{"key":"bibr14-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1007\/s00128-008-9361-5"},{"key":"bibr15-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1002\/9780470024539.ch2"},{"key":"bibr16-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.apgeochem.2008.11.010"},{"key":"bibr17-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1021\/es00044a013"},{"key":"bibr18-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.4319\/lo.1997.42.3.0519"},{"key":"bibr19-0734242X11408382","unstructured":"IUPAC (2010) IUPAC Compendium of Chemical Technology (Gold Book), electronic version release 2.2, Available from the IUPAC website at http:\/\/goldbook.iupac.org (accessed 5 May 2011)."},{"key":"bibr20-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/S0043-1354(98)00414-X"},{"key":"bibr21-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultramic.2004.12.004"},{"key":"bibr22-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.3354\/ame014205"},{"key":"bibr23-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1180\/002646101317018424"},{"key":"bibr24-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2010.07.058"},{"key":"bibr25-0734242X11408382","first-page":"1451","volume":"16","author":"\u00d8ygard JK","year":"2007","journal-title":"Fresenius Environmental Bulletin"},{"key":"bibr26-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.gca.2006.04.008"},{"key":"bibr27-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2007.09.077"},{"key":"bibr28-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-908X.2009.00010.x"},{"key":"bibr29-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1039\/b712709j"},{"key":"bibr30-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/S0927-7757(98)00874-7"},{"key":"bibr31-0734242X11408382","doi-asserted-by":"publisher","DOI":"10.1016\/j.wasman.2008.08.020"}],"container-title":["Waste Management &amp;
